B. is an immortal demigod.
Born over 80,000 years ago, he now works for the US military, particularly on the most dangerous missions, with the aim, with the help of scientists, of recovering his memory and his origins, in order to find a way to end his immortality.
Since his birth, he has been seen as a weapon of destruction, a monster that no one can stop, and which he himself cannot control when he enters a state of rage.
Despite everything, he remains a very wise man, with a perfect memory.
